Sclerotinia sclerotiorum (Lib.) de Bary (1884) is a fungal pathogen that causes substantial losses to a wide range of hosts worldwide. In Romania, Sclerotinia sclerotiorum is known for causing significant damage to plants in field crops and forced crops in greenhouses, warehouses, and silos. Since less are known about the epidemiology of Sclerotinia sclerotiorum in ornamental plants grown in natural landscapes the aim of this paper focuses on the pathogenetic characteristics of the fungus on woody ornamental plants as Forsythia sp. The Forsythia genus is a group of plants in the olive family (Oleaceae) with around 11 species that are primarily native to eastern Asia, with one species from Europe. In Roma-nia, Forsythia spp. Vahl is a perennial plant, appreciated and well known only as an ornamental plant named "golden-bells". This article describes the morphological characteristics and genetic investigation using PCR and Sanger sequencing of Sclerotinia sclerotiorum infection on ornamental plants of Forsythia × intermedia Zab. (F. suspensa × F. viridissima) tissue. Genomic DNA was amplified using ribosomal internal transcribed spacer region-specific primers, and samples were analyzed using sequencing techniques. Constant monitoring and insights record of Sclerotinia sclerotiorum across multiple hosts and time intervals can reduce potential spread and future economic losses in cultivated species.
